The Lowdown
Hey folks, Rusty here breakin’ it down for Kennebunk Beach over the next couple weeks in feet and miles per hour. The water is running a touch warmer than usual at 67°F, about 3°F above normal—so not bad for late summer.
First few days are flat. Saturday the 29th and Sunday the 30th offer barely a ripple: waves around 2–3 feet, weak energy (combined 33–64), with winds onshore or cross‑onshore. Monday the 31st through Wednesday the 2nd of September stays small, mostly 1‑footers with short periods. No reason to paddle out.
Thursday the 3rd of September is the real deal. Thursday morning brings a 10‑foot southeast swell (short 7‑second period), strong energy at 940. Wind is light east‑northeast at 9 mph, cross‑offshore, keeping the surface clean. That size is expert‑only. Thursday afternoon gets even better: same 10‑foot swell but wind shifts to northeast at 6 mph, offshore, giving you clean, powerful faces. Combined energy hits 1136 (very strong). If you’ve got the chops, this is your session—just know the crowds can show up.
Friday the 4th of September morning drops to 4‑5 feet from the east‑southeast, still offshore wind (northeast 6 mph), clean but only moderate energy (208). Afternoon the wind goes cross and the quality fades.
Then we hit a long lull. From Friday afternoon through Tuesday the 8th, waves barely reach 2–3 feet, winds mostly onshore or cross, with only brief glassy moments that don’t deliver. Wednesday the 9th of September offers a little something: 3‑4 feet south swell, cross‑off wind from north‑northwest, clean, energy 147. It’s surfable but nothing special. Thursday the 10th of September morning is glassy with a 3‑foot south‑southeast swell (10‑second period, energy 184)—again just ordinary. The rest of the second week stays tiny and messy.
So if you’re an expert, Thursday 3rd September afternoon is your one standout. Everyone else might want to wait for the next pulse. This spot can fire again quickly, so keep an eye on it.
Rusty out.

Information about the Kennebunk Beach Surf forecast
The above surf forecast table for Kennebunk Beach provides essential information for determining whether the surfing conditions will be good over the next 16 days. A general guide to surfing at Kennebunk Beach can be found by selecting the local surf guide option on the grey menu. Our Kennebunk Beach surf forecast is unique since it includes wave energy (power) that defines the real feel of the surf rather than just the height or the period. If you surf the same spot (Kennebunk Beach) regularly then make a mental note of the wave energy from the surf forecast table each time you go. Very soon you may start to choose your surf days based on the wave energy alone combined with our forecast of favourable offshore wind conditions. Our star ratings will help here and of course you will also find the usual wave height and period predictions on our surf forecasts as well as a full break down of the swell components under our advanced users option (to reveal that, click the little Einstein character under the tide times).
Further information to help with frequently asked questions about our surf forecast for Kennebunk Beach may be found under the help tab on the top menu and also by moving your mouse over the question marks on the surf forecast table itself. Please always bear in mind that the forecast is for near-shore open water and local factors at each surf break influence the actual breaking wave height, such as the beach / reef profile, water depths offshore and shelter.
